THE CYCLONE IS NOW OVER 25C WATER AND MOVING INTO PROGRESSIVELY COOLER WATER. SATELLITE INTENSITY ESTIMATES ARE ALL BELOW HURRICANE STRENGTH...BUT THERE WAS NO QUIKSCAT OVERPASS THIS EVENING TO SHOW IF MARIA IS STILL A HURRICANE. BASED ON THE COOLER WATER AND THE SATELLITE INTENSITY ESTIMATES...THE INITIAL INTENSITY IS DECREASED TO 60 KT. MARIA SHOULD WEAKEN SLOWLY FOR THE NEXT 36 HR AS IT LOSES TROPICAL CHARACTERISTICS OVER COOLER WATER...THEN RE-INTENSIFY AS AN EXTRATROPICAL CYCLONE AS IT INTERACTS WITH AN UPPER-LEVEL TROUGH. THE INITIAL MOTION IS 050/8...A LITTLE SLOWER THAN BEFORE. MARIA SHOULD CONTINUE NORTHEASTWARD IN THE WESTERLIES FOR 24 HR...THEN TURN MORE NORTHWARD WITH GRADUAL ACCELERATION AS IT INTERACTS WITH THE TROUGH.
